Hi All. Hope you can help with this. Looked at this vehicle for another garage as a favour. Using Solus found that temp of engine was 45oC and the guage reading 90oC. Never tested the temp sender which was in the bottom hose but suggested that the sensor was faulty. After fitting seemed ok but next day the same fault. Customer said that sometimes the guage goes half way before the engine is started when cold. The garage is sending the customer to me tomorrow to get checked out. Great Eh!! Any ideas welcome. Sensor part number was 800959481b and it was blue.
